NUT BLOCK.

Application filed Get0ber 15, 1921, Serial No. 507,943.

citizen ot the United States, residing at Cleveland, in the countv ot Cuyahoga and State ot' Ohio, have invented certain new ano use.tnl iinprovei iits in Nnt Looks, of which the following is a speciiication, refer once being had to the accompanying draw- 1n; s.

This invention relatos to certain improvements in nat looks, and it is an object of the invcntion to provide a nove improved device of this general char: cter which may he readily and e:liectively applied in working position and which mavalso he adjusted in order to permit removal of the nut, when desired.

Another object of the invention is to provide a novei and iinproved device of this gez*1erai character eni'hodying two relativelv ruovahlc members, one of said members beingadapted to he mounted upon the boit and the second ot said members being adapt cd to engage the coacting nut tor holding said nut against rotation.

The invention consists in the details of construction andin the combination and ar tngement of the several p rts ot my improved nut lock whereby certain important advantages are attained and the device 1I1* dered simpler, less cxpensive and otherwise more convenient and advantageous for use, as will be herenafter more fuily set torth.

T he novel features ot my invention will hereinafter be definitely claimed.

In order that 1':1V invention may be the better understood, i will now proceed to describe the same with re:terenee to the accom- *aan vingr drawings wherein:

Figure 1 is a view partl v in partl v in clevation illustrating a nut lock constrncted in accordence with an ein"oodi ment ot my inventicn and in applied position;

Figure 2 is a view in front elevation ilinstrting my improved nut lock, the coacting wor being indicated in :tragment;

Figure 3 is a view in elevetion ot the nut engaging member detached; end

lligure is an elevational view of the washer 'V.

As disclosed in the accompanving drawings, B denotes a boit herein disclosed as disposed through the web of a rai1 and the fish plate associated therewith. Coactingz; with the boit is a nut N.

section and My improved net lock comprises a Washer lV adapted to surround the holt B inwardly of the apphed nnt N. Extenthng outwardlv and laterally from the periphery of the washer V3 is a resil'ent or spring arni 1 terminating in a hook member 2 facing in a direction away from the nut N A denotes a suhstantialiy U-shaped member having its side arms 3 spaced apart a distance so as to suhstantially snngl receive therehetvwen the nut I se that, when the member Si is in working position, said nut is etfectivel v held against rotation and pan tieularly in a retrcgrade direction.

The intermediate or central portion 4 of? the member A. angular in cross section to provide the eonverging faces a while the inner face b et saio. pertion 1- is arcuate in cross section.

n practice, the hook portion 2 of the arm 1 constantly bears down upon the cinrved or arcuate portion b ot the intermediate part 4 of the member A whereby the meniber A is effectively maintained in working: position, as particularly illustralzed in Figure 1. yet at thesame time readil5 permite said member i to he swung outwardly and rearwardly to tree the arms 3 from the nut N so that said nut, when desired may be removed.

The relative angie of the faces a of the portion t of the member A is dependent upon the character of the worx with which the device is associated. When the member A. is in a position to took the nnt N, the inner face a is on such angie as to assnre the arms 3 assuming proper position with respect to the nat N. i

The peripherai portion of the washer lV- at point suhstantially diametricallv opposed to the arm 1 is straight, as at 5, said edge being oppositely chamtfered or beveled to permit said edge to have effective contact -with an outstanding rih or head G carried by the adjacent face of the work, said rib or head 6 serving to hold the washer .V against rotation around the holt B, therebv materially facilitating the funetioning of my inproved nut l0ci. v

The washer VV, which may be of a split type as indicated in Figure 4., is provided at diametrically opposed points with the out standing shonlders 7 with which the arms when in working position, are adapted to contact se that it is assured that said arms 3 will be maintained in the proper position te hold the nut N against rotation,

. out na::'ter cia1med.

From the foregoing description it is thought to he obvious that a nat lock con ructed in accordance with my invention is particularly weli adapted for use by reason of the convenience and faciiity with which it may be assembied and operated, and it wiii also he obvious that my invention is susce 3tibie of some chan e and modification without departing from the princpie's and spirit thereof and for this reason I donot wish to he understoed as iimiting myseif to he precise arrangement and formation of the several parts hcrein shown in carryn'g my invention in practiceexcept as herel claim:

l.*n combination with a mit, a ho1t and associated thercwith; a nat lock comprisi,ig a washer engaging the boit hetween the nut and the work, said wsher being p'rorided with a iateraiiy disposed reheing provided with a iateraiiy disposed re siiient arm terminatinS in a hook member facinp; the direction away from the nut, a suhstantiaily U-shaped member having its side arms spaced apart a distance to receive the nat therehetween the 1ntermed1ate por AOI1O the U-shaped member having a face arcuate in cross section with which the hook member of the arm engages from above, said U-shaped member resting upon the work, the intermediate portion of the U-shaped mem ber also being angular in cross section to provide con3ergingiaces, one of said faces contacting with the w rk when the U-shaped mern*er is in 1ockingposition with respect to nnt. r

In comhination with a nat, aboit and the wo'ri: associated therewith; annt lock comprising a washer engagingthe ho1t hetwcen the nat and the work, said washer being provided with a.1atei siiient am ter1ninating in a hook member iacing: the direction away from the nnt, a substantiaiiy U--shaped member having its side arins spaced apart a distance to receive the nat there-between the intermediate poron ot the Ushaped member having a face arcuate in crosssection with which the hooi:

n c n he arm engages from above, said US d member restmg upon the worr, said wash r oein prov1deci with ontstand b :1ng shouiders with which the arms of the U- shaped member are adapted to contact to maintain said arms in pro 3er position with respect to the nn.

In testimony whereof I hereunto aiii my signature.
